Maintenance and Storage
Maintenance
Before performing any maintenance on the trencher, it must be placed in maintenance mode.
(a.) Turn off engine
(b.) Move the control valves handle back and forth with the engine OFF to relieve hydraulic pressure.
(c.) Rest boom on the ground.
(d.) Unplug spark plug wire from spark plug
1.) Clean debris from the engine cylinder, cylinder head fins, blower housing rotating screen, and muffler areas. If
the engine is equipped with a spark arrestor muffler, clean and inspect it regularly (follow Briggs and Stratton
service instructions). Replace if damaged. Clear debris from movable parts, but only after the power source
is shut off.
2.) Check to be sure all nuts and bolts are tight to assure the equipment is in safe working condition.
3.) Inspect all hoses and fittings for wear and leaks. Perform all inspections and replace all damaged and worn parts prior
to starting the engine.
4.) Be sure all guards, shields, and safety features are in place.
5.) Inspect the suction filter.
